Dissolved Oxygen Calibration • Prior to calibration, the dissolved oxygen probe must be prepared and polarized .

The probe is continuously polarized when it is connected to the meter . When the probe is first connected or if the probe is disconnected for more than 60 minutes, connect the probe to the meter, connect the meter to a power source and wait 30 to 60 minutes for the probe to polarize . Disconnecting the probe for less than one hour will require 5 to 25 minutes for polarization .

• The meters will supply a polarization current to the dissolved oxygen probe even when the meter power is off . To maximize the meter battery life, unplug the probe if it will not be used for an extended period .

1 . Select one of the following calibration modes in the setup menu .

a . – An air calibration is performed in water saturated air using the calibration sleeve . This is the simplest and most accurate calibration . Due to the inherent differences between water saturated air and air saturated water, 102 .3% saturation will be displayed when the calibration reading is stable .

i . The highest possible accuracy is reached when calibration temperature is the same as the measuring temperature .

ii . Moisten the sponge or absorbent cloth in the calibration sleeve with distilled water and insert the probe into the sleeve without touching the water saturated material . For BOD measurements, this calibration can be performed in a BOD bottle .

b . – A water calibration is performed using water that is 100% saturated with air . Bubble air into a water sample and gently stir the sample to prevent the buildup of air bubbles on the dissolved oxygen probe membrane .

c . – A manual calibration is performed using a water sample with a known concentration of dissolved oxygen . This method can be used to calibrate the dissolved oxygen probe to the value achieved by a Winkler titration .

Dissolved Oxygen Technique


i . A manual calibration involves performing a Winkler titration and using that sample as a calibration standard . The oxygen level result from the titration is entered in a manual calibration as the dissolved oxygen value . This correlates the meter input to the Winkler titration . This method is inherently less accurate, due to the possibility of titration errors .

d . – A zero point calibration is performed in an oxygen-free solution . A zero point calibration is not generally required unless measurements will be taken below 10% saturation or 1 mg/L . Zero the probe when using a new membrane, using fresh filling solution or when measuring dissolved oxygen levels below 1 mg/L . An air calibration should be performed prior to the zero point calibration .

2 . Allow the probe and calibration standard (water saturated air, air saturated water, Winkler standard or oxygen-free solution) to reach equilibrium .

3 . In the measurement mode, press until the arrow icon points to the bottom line, press until the % sat or mg/L icon is shown and press to begin the calibration .

4 . Wait for the dissolved oxygen reading to stabilize .

a . If an air calibration is performed, the meter will display 102 .3% and automatically return to the measurement mode .

b . If a water calibration is performed, the meter will display 100 .0% and automatically return to the measurement mode .

c . If a manual calibration is performed, wait for the mg/L icon to stop flashing and enter the dissolved oxygen value by pressing until the first digit to be changed is flashing, press / to change the value of the flashing digit and continue to change the digits until the meter displays the correct dissolved oxygen value . Once the dissolved oxygen value is set, press until the decimal point is in the correct location .

d . If a zero point calibration is performed, the meter will display 0 .00 and automatically return to the measurement mode .



Dissolved Oxygen MeasurementNote: Turn on the automatic datalog feature to send measurements to the meter datalog at the frequency specified in each measurement mode. Refer to the Data Archiving and Retrieval section for details. If the automatic datalog feature is off, connect the meter to a printer or computer to record the measurements.

Chapter IX RDO® Optical Dissolved Oxygen TechniqueNote: The RDO optical dissolved oxygen meters have serial numbers that begin with R (i.e. R12345). Only the RDO meters are compatible with the RDO optical dissolved oxygen sensors.

RDO Cap OverviewThe RDO sensor has an internal clock that counts down the 365 day lifespan of a new RDO cap . The countdown begins when the RDO cap is installed on the RDO sensor, the sensor is connected to the meter and the first measurement is taken . The 365 day countdown cannot be reset or changed once the first measurement is taken . Each RDO cap has a unique serial number that is recognized by the RDO sensor, so reinstalling the cap will not reset the countdown .

Note: The power to the meter must be turned off when a new RDO cap is installed on the RDO sensor. Once the RDO cap is installed, turn the power to the meter on and the new cap information will be sent to the meter.

Troubleshooting


General Troubleshooting

Problem: The display freezes and the measurement values will not change .

Solution: The meter is in the AUTO-READ measurement mode (the AR icon will appear in the top, right corner of the display) . Press to start a new reading or select another measurement mode in the setup menu .

Problem: When I press the meter displays .

Solution: The meter is printing and cannot enter the calibration mode until the printing is done . This should rarely occur if the meter is set to a 9600 baud rate . If the meter is at a lower baud rate, the delay will be longer .

Problem: The meter did not accept the change I made in the setup menu .

Solution: After making a change in the setup menu, press until the arrow icon points to the top line (confirms the change) and then press to save the change and return to the measurement mode .

Problem: How do I abort a calibration?

Solution: Press and hold to abort any meter operation and return to the measurement mode .

Problem: The printout is a string of numbers and units with commas .

Solution: The output format in the setup menu is set to the computer output or the printer baud rate is set incorrectly in the setup menu . Change the output format to the printer output in the setup menu . Change the baud rate to the correct value for the printer that is being used .

Problem: When I press the stirrer button, the stirrer doesn’t work .

Solution: The current stirrer setting is off . Set the speed to 1 through 7 in the setup menu .

Problem: The timed measurement time entry screen does not appear in the setup menu .

Problem: I cannot tell if I have the Star Plus meter or the Orion Star meter .

Solution: When the meter is powered on, the Star Plus meters with enhanced features will display with the meter revision number ( or similar) and proceed to the measurement mode .

Troubleshooting


pH TroubleshootingProblem: The meter does not recognize the pH buffer value during calibration .

Solution: Verify that the correct buffer set was selected in the setup menu . The meter uses the raw mV reading of the electrode to recognize a buffer during calibration . As the electrode ages or becomes dirty, its mV readings will drift and you will need to manually enter the pH buffer value when calibrating .

SE TroubleshootingProblem: It takes several minutes for the readings to stabilize during a calibration .

Solution: The concentration range in the setup menu is set to low . Change the concentration range to high . The ISE resolution is set to 3 digits in the setup menu . Change the ISE resolution to 2 digits for faster stabilization of the readings .

Problem: When I use the automatic blank correction setting and calibrate an ISE, the meter gives a slope that is too low or cannot be manually checked .

Solution: Turn the automatic blank correction setting off in the setup menu .

Conductivity TroubleshootingProblem: The meter does not recognize the conductivity standard during

calibration .

Solution: Verify that the default cell constant was entered in the setup menu . The cell constant is usually printed on the conductivity probe cable . Verify that the conductivity standard is one that is programmed into the meter . Re-calibrate with a fresh standard .

Problem: The temperature coefficient value does not appear in the setup menu .

Solution: The current temperature compensation setting is nonlinear or off . Change the temperature compensation to linear and the next screen will be the temperature coefficient value entry screen .

Problem: The measurement is out of range when it should be in range .

Solution: Check that the conductivity probe is fully immersed in the solution . Verify that the cell constant is correct for the conductivity probe that is connected to the meter . Verify that the cell type selected in the setup menu is set to Std .

Troubleshooting


Dissolved Oxygen TroubleshootingProblem: The manual barometric pressure entry screen does not appear in the

setup menu .

Solution: The barometric pressure compensation is set to automatic in the setup menu . Change the barometric pressure compensation to manual and the next screen will be the manual pressure entry screen .

Problem: The manual salinity factor entry screen does not appear in the setup menu .

Solution: The salinity correction is set to automatic in the setup menu . Change the salinity correction to manual and the next screen will be the salinity factor entry screen .

Problem: The AUTO-STIR BOD probe does not turn on when the button on the probe is pressed .

Solution: The read type must be set to AUTO-READ in the setup menu and the stirrer speed must be set from 1 to 7 to initiate a measurement and start stirring by pressing the button on the AUTO-STIR BOD probe .

RDO® Optical Dissolved Oxygen TroubleshootingProblem: The meter displays an error 881 message and will not take a dissolved

oxygen measurement .

Solution: Turn the meter off, replace the old RDO cap with a new cap and turn the meter on . This should clear the error message .

Appendix A Meter Setup Menu FeaturespH Setup Menu FeaturesAutomatic buffer recognitionThe Orion Star and Star Plus pH meters are capable of automatically recognizing pH 1 .68, 4 .01, 6 .86, 7 .00, 9 .18, 10 .01 and 12 .46 buffers during a pH calibration . During a calibration, the meter uses the selected buffer set and the raw mV reading of the pH electrode in the buffer to recognize and display the buffer value at the measured temperature . The raw mV value must be about ± 30 mV from the theoretical mV reading of the buffer in order for the meter to automatically recognize the buffer .

Buffer mV Range Buffer mV Range Buffer mV Range

1.68 +285 to +345 7.00 - 30 to + 30 10.01 -207 to -147

4.01 +207 to +147 9.18 -99 to -159 12.46 -293 to -353

6.86 +38 to -22

Dissolved Oxygen Setup Menu FeaturesBarometric Pressure CompensationThe Orion Star and Star Plus dissolved oxygen meters have an internal barometer that is used for pressure compensated dissolved oxygen readings . The meter can also use manual barometric pressure compensation if dissolved oxygen is measured with a submerged probe or in a pressurized vessel . The pressure must be entered as mm Hg . 1 mm Hg = 0 .03937 inch Hg = 1 .3332 hPa (mBar) = 0 .01934 PSI .

Salinity CorrectionAutomatic salinity correction for dissolved oxygen readings is available on Orion Star and Star Plus dissolved oxygen meters that have a conductivity measurement mode . The meter uses the conductivity value read by the conductivity probe to calculate the salinity correction factor and applies the factor to dissolved oxygen readings reported as mg/L .


The meter can also use manual salinity correction for dissolved oxygen readings reported as mg/L . The manual salinity correction factor must be entered as ppt (parts per thousand) .

Conductivity Setup Menu FeaturesTemperature Compensation and Reference TemperatureThe Orion Star and Star Plus conductivity meters have the ability to use a temperature compensation feature that calculates and displays the conductivity measurements at a reference temperature of 5 °C, 10 °C, 15 °C, 20 °C or 25 °C (Orion Star meters have a reference temperature of 15 °C, 20 °C or 25 °C only) . The temperature compensation can be set as linear for most aqueous samples, non-linear for ultra pure and low ionic strength samples or off for non-temperature compensated conductivity measurements .

Meter Setup Menu Features


The closer the sample temperature is to the selected reference temperature, the more accurate the conductivity measurement will be, especially if the temperature compensation coefficient is estimated or inaccurate .

The conductivity of a solution with a specific electrolyte concentration changes with temperature and this relationship is described by the temperature coefficient of the solution . The meter has a default temperature coefficient of 2 .1 percent change in conductivity per ˚C, which is representative of many aqueous samples .

Total Dissolved Solids (TDS)The Orion Star and Star Plus conductivity meters measure TDS as the total amount of dissolved inorganics in a solution . The dissolved inorganics carry a current that is measured by the conductivity probe . Since there is a direct relationship between conductivity and TDS, conductivity readings are used to estimate the presence of inorganics . The user must enter a TDS factor between 0 .01 and 10 mg/L in the setup menu .

The standard method of determining TDS involves evaporating a sample to dryness at 180 ˚C and weighing the residue . The TDS factor is calculated by taking the residue weight and dividing it by the sample conductivity . Subsequent conductivity readings are multiplied by the TDS factor to determine the TDS value of the sample .



Automatic CalibrationThe Orion Star and Star Plus conductivity meters are capable of automatically recognizing 100 µS/cm, 1413 µS/cm and 12 .9 mS/cm conductivity standards when the nominal cell constant of the conductivity probe is entered in the setup menu . For the meter to recognize the conductivity standard, the entered cell constant must be accurate within a factor of 3 . For example, if the actual cell constant is 1 .0 cm-1, entering a nominal cell constant in the range of 0 .3 cm-1 to 3 .0 cm-1 would allow the meter to identify the conductivity standard and perform the automatic calibration .

SE Setup Menu FeaturesConcentration Range The Orion Star and Star Plus ISE meters can be set for a high or low ISE concentration range that is used to determine the calibration stability criteria . If a high ISE concentration range is selected, the meter will perform a normal calibration with no delay in displaying the calibration standard value . If a low ISE concentration range is selected, the meter will wait about three to five minutes before displaying a stable reading for the calibration standard values . The delay will depend on the species being measured and the concentration of the calibration standards . The low ISE concentration range is designed to improve the accuracy of low concentration measurements by allowing the electrode to have a longer amount of time to stabilize in the calibration standards .

Automatic Blank CorrectionThe Orion Star and Star Plus ISE meters have an ISE automatic blank correction feature that uses an algorithm to compensate for the non-linearity of the ion selective electrode in low-level standards and samples . Since the automatic blank correction feature requires the use of a set of non-linear equations that can only be calculated numerically, the user cannot analytically verify the calibration and the average slope value that is displayed on the meter may be outside of the slope range that is specified in the electrode user guide . In applications were analytical verification is required, the automatic blank correction feature should be turned off .
